Build 2

[Johnsmith]

 I got a lot of work done between yesterday and this morning.  I'll probably need to buy a new bench top drill press. I followed the assembly instructions when I bought
mine 3 years ago. It said to use the work surface parts are placed on to push the chuck (drill head) into place. This bent something and the holes don't go straight
through the board. Next weekend I'll be able to finish the parts I've got the primary shape and dimensions for. I'll be able to post some before and after pictures so
everyone will know how I'm going about making parts. My new tools allowed me to do more in less time. I even made a 1 3/4 inch by 1 3/4 inch by 20 inch long block.
The way I was going to make the brackets to hold the parts that will be used like a pool cue went from 4 different pieces to being only 1 piece.  The image shows how
I changed the bracket. And basically yesterday I wasted a lot of time trying to make an overly complicated design. A round hole will also have 4 points of contact with a
square dowel. There will be room for the dowel to move inside the hole. 4 points of contact means less resistance. If a 1 inch in diameter hole is drilled, then there will
be 1/16th of an inch of play at all 4 corners. Doing a lot math is helpful for something like this or any build.

p.s., you can see where I tried routing a radius. End grain tends to tear. If you consider the long arm coming towards you, when the triangle by it's the square dowel, everything will kick to the right. The square blocks will be attached to the arm. I should be able to rout the holes they need. Not as simple as drilling a hole but I won't need to buy another drill press.

 I've been checking the alignment on everything. With my previous 4 weight test, it's possible the axle was rubbing against the inside of the disc.
With the first image, the weight wheels have only a small gap between them. Why this matters is for when the cue will kick them out. The second
image shows where I used screws to lock the axles for the wheels in place. I'll need to change to a 1/2 x 2 x 3 5/8 board. Then they'll be solid and
won't have any screws interfering with their moving up to the cue.
I might only have Sunday morning to get any real work done so will need to be prepared to make the best use of my time. I am also going to start
doing an actual design for the next iteration of this build. I've already ripped a lot of wood that I'll need for it. Most likely it will be a completely new
build. Then the difference between a prototype (learning how to build it) and what it allows for can be seen.

 This is the next build that I've already started work on. By having the arms extend upward at a 45º before move outward is the weight wheels
will be able to rollout above the level of the axle. This will increase the amount of torque that the wheel can generate. It will have a radius of 43
inches or 1.09 m.
I'll need to do a couple of drawings so I'll get the details right. It will have a ring for pulleys. That will be a part of the hub assembly and will not
be a part of what I'm showing now. And in this build I will be doing a lot more detail work. And this is why I've bought so many new tools for. I
know what I'm doing now.And it might take only 1 or 2 months for this build to be built instead of a few years. An example is I'll probably have
the hub core finished this weekend. That's the octagon in the middle of the wheel. And I like how well it fits together. I used 8 pieces of wood and
they formed a nice square. I'm gluing together where the red clamps are. This is because the fitting on top will need to be inserted before all 4
sides can be assembled or if you like the Borg Collective, they will be assimilated.
I have ordered boot laces for retraction lines and sometime next week I'll have them. I have some aluminum grommets that I can compress so
they'll be locked onto just as wires or cables are secured. If you look at a utility pole that has wires supporting it, look at the banding they use. I'm
just using smaller grommets which can be crimped.

p.s., SketchUp does have a smoothing tool I could use to make the rims more circular. That could take up a lot more memory on my computer
while not changing what I need to know. Basically if things work out for me and I continue on projects like this, I'll need to get a better computer
and subscribe to SketchUp Pro. At the moment this is just a serious hobby for me and inexpensive tools and computers work for now.

p.s.s., with the long arms that go away from the center of the wheel, their length doesn't matter. This is because I can trim them close to the
outside of the rim before routing them flush with it. The difficult part will be getting the rim to be circular. At 86 in. or 2.18m in diameter, it's not small.
And when it will be assembled in sections this might require allowing for it to be trimmed after it's on the wheel. And that is not a fun thing to think
about. But builds like this do present their challenges. It's like these 3 kids saw an obstacle and went up and over it.

Good job, have you an idea when you device will be finished ?

Good job, have you an idea when you device will be finished ?

Thanks. It could be another 2 to 3 weeks. I'm hoping I can make most of the parts I need tomorrow. Once I have all of the mechanical
items finished I'll need to work on the catch and release mechanism. Then the lines that hold onto the weights can be released. It
shouldn't be too difficult to get that working right.

p.s., what is a bit frustrating everyone is I bought a shop vac and as it turns out they do not make adapters so they can be connected
to the dust ports on miter saws or table saws. Fortunately I happen to have some neoprene and will need to make my own. Then with
shrink wrap they might even look professionally made.If they work out well then I might advertise on Ebay for custom made vacuum
couplings. That's where I was going to make a sleeve for my tablet.
But for tomorrow I happened to have bought duct tape. Am trying to work cleaner.
